    Opis:
    Objectives: Night shift work has been linked to some chronic diseases. Modification of lifestyle by night work may partially contribute to the development of these diseases, nevertheless, so far epidemiological evidence is limited. The aim of the study was to explore association between night shift work and lifestyle factors using data from a cross-sectional study among blue-collar workers employed in industrial plants in Łódź, Poland. Material and Methods: The anonymous questionnaire was self-administered among 605 employees (236 women and 369 men, aged 35 or more) - 434 individuals currently working night shifts. Distribution of the selected lifestyle related factors such as smoking, alcohol drinking, physical activity, body mass index (BMI), number of main meals and the hour of the last meal was compared between current, former, and never night shift workers. Adjusted ORs or predicted means were calculated, as a measure of the associations between night shift work and lifestyle factors, with age, marital status and education included in the models as covariates. Results: Recreational inactivity (defined here as less than one hour per week of recreational physical activity) was associated with current night shift work when compared to never night shift workers (OR = 2.43, 95% CI: 1.13-5.22) among men. Alcohol abstinence and later time of the last meal was associated with night shift work among women. Statistically significant positive relationship between night shift work duration and BMI was observed among men (p = 0.029). Conclusions: This study confirms previous studies reporting lower exercising among night shift workers and tendency to increase body weight. This finding provides important public health implication for the prevention of chronic diseases among night shift workers. Initiatives promoting physical activity addressed in particular to the night shift workers are recommended.

    Opis:
    Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity. The study involved 2 phenomena typical for the behavior of the human pupil: pupillary reflex and pupillary movements. The 1st phenomenon is related to the pupillary light reflex (PLR), which presents the results of physiological adaptation mechanisms of the human eye. The pupillary unrest index (PUI) is an additional parameter referring to the tendency for instability of the pupil. Material and methods Indicators of these 2 mechanisms were assessed under the same experimental laboratory conditions. Assessment was conducted on a group of volunteers (N = 10) during 4 controlled series of measurements performed at night. Pupillary reflex parameters associated with PLR and pupillary unrest index (PUI) were recorded using F²D Fit-For-Duty, a commercially available system made by AMTech Pupilknowlogy GmbH. Baseline pupil diameter, oscillations, reflex latency, maximum reaction time, pupil constriction time, pupil dilation time, and constriction amplitude were recorded. Results As a result of the study, we were able to demonstrate correlation and confirm the usefulness of PLR and PST methods in the assessment of sleep deprivation. Parameters of PLR that may indicate human fatigue were identified. The effect of light impulse sequences on the dynamics of pupillary reflex and the relationship between PUI (pupillary unrest index) measurement duration and sleepiness assessment validity, were assessed. Conclusions The results of the pilot studies were sufficient to develop minimum requirements for a PLR sensor that would be capable of estimating the level of fatigue with accuracy of a PUI method, but at a 5 times faster rate.

    Opis:
    ObjectivesPhysical activity (PA) is important for the prevention and management of numerous diseases and may have a positive effect on ability to work. The study aimed to assess the level of occupational and leisure time PA of soldiers during the COVID-19 pandemic and to explore whether there was a relationship between PA and perceived work ability.Material and MethodsThe study involved 305 men and 68 women who were territorial army soldiers aged 18–55 (M±SD 32.9±9.01). The Seven-Day Physical Activity Recall (SDPAR) and the Work Ability Index (WAI) were used.ResultsThe level of self-reported PA for the studied soldiers was relatively high; 80% of them met the recommendations of the WHO and were characterized by having a good (60%) or excellent (20%) WAI status. The level of occupational PA of male soldiers was higher than the level of leisure time PA, and they indicated higher levels of occupational PA and leisure time PA during the workweek than the weekend.ConclusionsCurrent work ability in comparison to the best in life and work ability related to the physical requirements of the work were positively correlated with leisure time PA. Work ability related to physical requirements was also positively correlated with occupational and total PA, and work ability related to mental requirements was positively correlated with total PA. The study supports the relationship between PA and several aspects of work ability.

    Opis:
    Background Back pain represents one of the most common diseases across various populations of workers worldwide. This study analyzes the prevalence and severity of back pain, based on selected demographic variables, and the relationship with physical activity among school teachers. Material and Methods The study included 998 professionally active teachers (840 females and 158 males) from the southern part of Poland. Validated psychometric tools, namely: 1) for evaluation of disability due to back pain – a Polish version of the Oswestry Disability Index (ODI) and Neck Disability Index (NDI), 2) for physical activity assessment – the Subjective Experience of Work Load (SEWL) as well as the authors’ supplementary questionnaire, addressing demographic and anthropometric variables were used. Results There was no correlation between age and the NDI scores in females (r = 0.027), in contrast to males (r = 0.202; p ≤ 0.05). Statistically significant correlations (p ≤ 0.05) were reported between: age and the ODI, in both females (r = 0.219) and males (r = 0.180). No associations between the body mass index (BMI)-ODI, and BMI-NDI were found. In the case of women, disability related to low back pain (LBP) had a negative impact on the indicators of their activity during work, sports, and leisure time. In the case of men, the NDI and ODI scores did not differ, based on activity indicators. Conclusions Our findings confirm that back pain represents a serious concern among teachers. Age appears to be a prognostic factor, while no association between the BMI and LBP has been revealed. The limitation of physical activity leads to more frequent back pain. Med Pr 2015;66(6):771–778
    Wstęp Ból pleców to na całym świecie jedna z najczęściej spotykanych dolegliwości zdrowotnych w różnych populacjach pracowników. Celem badania była ocena występowania i nasilenia dolegliwości bólowych pleców wśród nauczycieli polskich szkół w powiązaniu z ich aktywnością fizyczną i zebranymi zmiennymi demograficznymi. Materiał i metody W badaniu uczestniczyło 998 czynnych zawodowo nauczycieli (840 kobiet, 158 mężczyzn) z południowej Polski. Wykorzystano następujące narzędzia psychometryczne: 1) do oceny niepełnosprawności z powodu bólu pleców – polską wersję wskaźnika niepełnosprawności Oswestry (Oswestry Disability Index – ODI) i szyjny indeks niepełnosprawności (Neck Disability Index – NDI), 2) do oceny aktywności fizycznej – subiektywną ocenę wykonywanej pracy (Subjective Experience of Work Load – SEWL) oraz autorski kwestionariusz z pytaniami dotyczącymi zmiennych demograficznych i antropometrycznych. Wyniki Nie wykazano zależności między wiekiem a NDI w grupie kobiet (r = 0,027), w przeciwieństwie do mężczyzn (r = 0,202; p ≤ 0,05). Różnice istotne statystycznie (p ≤ 0,05) uzyskano między zmiennymi: wiek i ODI (u kobiet: r = 0,219, u mężczyzn: r = 0,180). Nie wykazano istotności statystycznej między wskaźnikiem masy ciała (body mass index – BMI) a ODI ani między BMI a NDI. U kobiet z dolegliwościami bólowymi kręgosłupa stwierdzono niski poziom aktywności fizycznej w czasie pracy, w trakcie uprawiania sportu i spędzania wolnego czasu, natomiast u mężczyzn nie odnotowano takiej zależności. Wnioski Uzyskane wyniki potwierdzają, że ból pleców jest poważnym problemem wśród nauczycieli. Wiek jest czynnikiem prognostycznym, natomiast nie odnotowano związku między BMI a bólami kręgosłupa. Ograniczenie aktywności ruchowej wiąże się z częstszymi dolegliwościami bólowymi kręgosłupa. Istnieje potrzeba wdrażania wśród nauczycieli programu promocji zdrowego stylu życia, ze szczególnym uwzględnieniem aktywności ruchowej. Med. Pr. 2015;66(6):771–778
